The LHCf experiment has been designed to precisely measure forward neutral particle spectra produced in proton-proton collisions at LHC up to an energy of 14 TeV in the center of mass system. These measurements are of fundamental importance to calibrate the Monte Carlo models widely used in the high energy cosmic ray (HECR) field, up to an equivalent laboratory energy of the order of 10 17 eV. In 2009-2010 the experiment has completed the p-p data taking at √ s = 0.9 TeV and √ s = 7 TeV and the

... detectors have later on been removed from the tunnel region, when the LHC luminosity increased above 10 30 cm −2 s −1 . The detectors are now being upgraded in view of the p-p run at √ s = 14 TeV. In this paper the first results on the inclusive photon spectrum measured by LHCf is reported. Comparison of this spectrum with the model expectations show significant discrepancies, mainly in the high energy region. In addition, perspectives for future analyses as well as the program for the next data taking period will be discussed.
